Master and slave?
How do I describe the operation of the machines I use/set up where the slave unit is a PLC controling an arm, and the machine is the master that sends signals to the PLC saying "get on with it" (then waits for the PLC to go "done now you heap of junk")
But the whole 'words you cant use' nonsense is getting way out of hand and its largely due to some social sciences person taking offence on someone else's behalf while never bothering to ask if said person IS offended.
Anyways... I have a nice afternoon working on the new edition of newspeak, right after watching 'Blazing saddles' a film almost designed to offend everyone*
*everyone in this context means everyone without a sense of humour...
